<para>
|
||
|
|
<function>msg_send</function> sends a <parameter>message</parameter> of type
|
||
|
|
<parameter>msgtype</parameter> (which MUST be greater than 0) to a
|
||
|
|
the message queue specified by <parameter>queue</parameter>.
|
||
|
|
</para>
|

|
|
<para>
|
||
|
|
If the message is too large to fit in the queue, your script will wait
|
||
|
|
until another process reads messages from the queue and frees enough
|
||
|
|
space for your message to be sent.
|
||
|
|
This is called blocking; you can prevent blocking by setting the
|
||
|
|
optional <parameter>blocking</parameter> parameter to &false;, in which
|
||
|
|
case <function>msg_send</function> will immediately return &false; if the
|
||
|
|
message is too big for the queue, and set the optional
|
||
|
|
<parameter>errorcode</parameter> to EAGAIN, indicating that you should
|
||
|
|
try to send your message again a little later on.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
The optional <parameter>serialize</parameter> controls how the
|
||
|
|
<parameter>message</parameter> is sent. <parameter>serialize</parameter>
|
||
|
|
defaults to &true; which means that the <parameter>message</parameter> is
|
||
|
|
serialized using the same mechanism as the session module before being
|
||
|
|
sent to the queue. This allows complex arrays and objects to be sent to
|
||
|
|
other PHP scripts, or if you are using the WDDX serializer, to any WDDX
|
||
|
|
compatible client.

||
|
|
</para>

<para>

Upon successful completion the message queue data structure is updated as
|
||
|
|
follows: <parameter>msg_lspid</parameter> is set to the process-ID of the
|
||
|
|
calling process, <parameter>msg_qnum</parameter> is incremented by 1 and
|
||
|
|
<parameter>msg_stime</parameter> is set to the current time.
|
||
|
